[0028] S401: Deploy the verification node through the multi-factor authentication matrix according to the legal identity feature set, wherein the multi-factor authentication matrix is ​​composed of the multi-factor authentication elements, and the calculation formula of the multi-factor authentication elements is:

[0029]

[0030] Wherein, H is the multi-factor authentication element, p represents the preset verification range, q represents the repeated verification range, θ1 represents the verification deviation, θ2 represents the verification fuzzy value, and t represents the number of verifications;

[0041] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0042] Figure 1 It is a system architecture diagram of the present invention. DETAILED DESCRIPTION

[0043] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0044] See also Figure 1 A metaverse digital asset identity authentication system includes a user identity legal construction module, a user identity authentication module, and a multi-factor identity authentication module; the user identity legal construction module performs identity information identification on users in the metaverse system, and performs identity data modeling based on the user identity information to ensure the authenticity of the user identity; the user identity authentication module verifies the user identity information through a smart contract protocol and establishes trust in digital asset content; the multi-factor identity authentication module verifies the user identity of the digital asset content through a multi-factor identity authentication matrix deploying verification nodes to establish trust in the output of digital asset content.

[0045] The construction of the user's legal identity by the user identity legal construction module includes:

[0046] S101: Acquire a first knowledge factor and a first real-time biometric factor of the user, where the knowledge factor includes a password and a PIN code, and the real-time biometric factor includes facial recognition, fingerprint, and palm print;

[0047] S102: grouping user identity information by support vector machine based on knowledge factors and real-time biological factors;

[0048] S103: Generate more attribute data by modeling user identity through data enhancement technology to construct a legal identity dataset;

[0049] S104: Extracting a legal identity feature set through principal component analysis based on the legal identity data set.

[0050] When steps S1, S2, S3, and S4 are all completed, the legal user identity information is obtained.

[0051] Furthermore, in order to support users having multiple avatars in the metaverse system, the user identity legal construction module encrypts the legal identity feature set through a private key and creates a unique identity identifier, creates a unique avatar identifier for each avatar, and associates the unique identity identifier with the unique avatar identifier. By associating the unique identity identifier with the unique avatar identifier, the avatar can be legalized and traceable, and storage can be reduced.

[0052] The user identity authentication module verifies user identity information through smart contract protocols and establishes trust in digital asset content, including

[0053] S201: Establishing a user identity record by recording the user's blockchain address and unique identity identifier through a smart contract;

[0054] S202: Determine whether the user identity record matches the legal user identity information.

[0055] Among them, whether the user identity record matches the legitimate user identity information specifically includes:

[0056] S301: When the user identity record successfully matches the legitimate user identity information, the virtual object is allowed to generate digital asset content, including:

[0057] S401: Hash-encrypt the source code of the virtual object to obtain a source code hash value;

[0058] S402: Record the source code hash value to the digital asset list of the Metaverse;

[0059] S403: Create or open transaction attributes of virtual objects;

[0060] When steps S201, S202, and S203 are all completed, it is confirmed that the virtual object generates digital asset content;

[0061] S302: When the user identity record does not successfully match the legal user identity information, it is impossible to generate digital asset content based on the virtual object.

[0062] Furthermore, the integrity and ownership of digital asset content can be automatically verified through smart contracts.

[0063] In steps S301 to S302, the identity authentication module assumes that the virtual object can be digitalized as an asset. According to the legitimate user identity information output by the user identity legal construction module, the user's blockchain address and unique identity identifier are recorded through the smart contract to establish a user identity record. The user identity record is matched with the legitimate user identity information to establish digital asset content trust. It should be noted that the user identity record is verifiable and cannot be tampered with.

[0064] The multi-factor authentication module uses identity addressing to verify the user's identity against the digital asset content to establish the trust of the digital asset content output, including:

[0065] S401: Deploy verification nodes through a multi-factor authentication matrix according to the legal identity feature set. The multi-factor authentication matrix is ​​composed of multi-factor authentication elements. The calculation formula of the multi-factor authentication element is:

[0066]

[0067] Where H is a multi-factor authentication element, p represents the preset verification range, q represents the repeated verification range, θ1 represents the verification deviation, θ2 represents the verification fuzzy value, and t represents the number of verifications;

[0068] S402: According to the verification node, collecting the second knowledge factor and the second real-time biological factor of the user;

[0069] S403: Convert the second knowledge factor and the second real-time biometric factor into a multi-factor authentication data packet and transmit it to a corresponding position of the multi-factor authentication matrix;

[0070] S404: Determine whether the multi-factor identity authentication data packet matches the legal identity feature set.

[0071] Among them, comparing the multi-factor authentication data package with the legitimate identity feature set specifically includes:

[0072] When the multi-factor authentication data package successfully matches the legitimate identity feature set, the digital asset content output trust is established and the digital asset content is allowed to be output;

[0073] When the multi-factor authentication data package fails to match the legitimate identity feature set, the output of digital asset content is not allowed and an alert is issued.

[0074] Steps S401 to S403 verify that the user in the Metaverse system has deployed verification nodes through the multi-factor authentication matrix according to the legal identity feature set by re-collecting the user's knowledge factors and real-time biological factors through the multi-factor authentication module, ensuring that the digital asset content is output by a legal user, ensuring the efficiency and quality of verification. In addition, when the multi-factor authentication data packet does not match the legal identity feature set, an early warning will be issued, which guarantees the legitimacy and security of the output of digital asset content to a certain extent.

[0075] In summary, the system of the present invention includes a user identity legal construction module, a user identity authentication module, and a multi-factor identity authentication module. The embodiment of the present invention performs identity information identification on users in the Metaverse system in the Metaverse system, and performs identity data modeling based on the user identity information to ensure the authenticity of the user identity. The user identity information is verified through the smart contract protocol and the digital asset content trust is established. The multi-factor identity authentication module verifies the user identity of the digital asset content through the multi-factor identity authentication matrix deployment verification node to establish the digital asset content output trust. With the digital assets of the Metaverse as the core, user identity authentication is performed from the three links of user identity legal construction, digital asset content generation, and digital asset content output, so that attackers cannot maliciously generate or output digital assets, and the processing through this identity authentication system can ensure that Metaverse users can safely process digital assets on the basis of ensuring content trust in any scenario, and maximize the trust of digital asset content and the authenticity of user identity in the Metaverse.
